Pond Boss Forums INTRO Common Pond Q&A (archives) Filamentous Algae, aka Pond Scum/Moss - Management

Many have had good success using the correct number and size of blue tilapia for eating filamentous algae FA in ponds. Blue tilapia are reportedly best because they are more prolific than many other strains of tilapia and blue strain variety tolerates lower water temperatures that allows them to eat algae longer in the FA growing season. Larger sized tilapia for stocking are important to avoid LMB predation. Larger sized tipalia will also quickly spawn after stocking to produce lots of young tilapia who eat lots of newly sprouting filamentous algae - FA. They eat most all forms of fialmentous algae. When algae is eliminated they reportedly eat some organic muck that conatin nutritious bacteria from the sediments.

The following is a newspaper article telling about blue tilapia for algae control in water bodies.
